We use this product everyday at work. We have tried a few different types of disposable masks and have had some difficulty finding one that was inexpensive but provided the correct protection for our uses. This mask fits a variety of faces and doesn't leave that outline on your face that some less quality masks leave behind. Every since we switched to this mask I have had no complaints about people feeling like they can't breath, do the masks thickness, or that the mask is not fitting right, or that it is to thin and dust particles are still getting in. Even people that have breathing problems, like Asama, have had no problems with this mask. I would and have recommended this to other people.
